Broadened Auditory Spectrum
(ULTRASOUND OR INFRASOUND)
This quality enables the character to hear outside the range of normal metahuman hearing. They can either hear ultrasonic, high-frequency sound (including ultrasound emitters) or infrasonic, low-frequency sound. The character must choose which kind of frequency they can hear upon selecting the quality, and the quality may be selected twice, once for each frequency. They cannot choose or control any particular frequency within the selected spectrum. This ability allows the character to make a Perception Test to detect communication or sounds within his chosen frequency band and adds +1 to the limit of Perception Tests involving sound. As this kind of hearing can be considered always on, noises inaudible to others may sometimes distract or deafen the character. This quality results in minor visible changes to the size and structure of the outer ear.
Broadened Auditory Spectrum is incompatible with any Earware (p. 453, CRB).
